HARVESTER-CUTTER.

EPBCIEICATION forming part of Letters Patent No. 351,004, dated October19,1886.

Application filed January 6, 1&6. Serial No. 187,808.

To all whom it may concern.-

Be it known that I, LEONARD STUDY, acitizen of the United States,residing at McIaul, in the county of Fremont and State of Iowa, haveinvented certain new and useful Improvements in Harvester-Cutters; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to cutting apparatus for reaper and mowingmachines; and it consists in combining therewith an attachment toprevent the rear edge of the cutter-bar and the front edge of thefingenbar from rubbing together, thereby reducing the friction and thewear of the parts, by which a lighter draft is secured.

The object'of the invention is to secure a parallel motion of thecutter-bar during its reciprocating movement and prevent the rear edgeengaging with the finger-bar.

To these ends it consists in the novel features hereinafter more fullyset forth and claimed.

In the drawings, Figure l is a plan View of a cutting apparatus providedwith my attachment, parts being broken away to show its construction.Fig. 2 is an inverted plan view of the case with the operating parts inposition. Fig. 3 is a perspective detail of a portion of the cuttingapparatus and one end of the case, showing the means for fastening it inplace; and Fig. 4 is a similar View showing the opposite side of thecase and the means by which it is held in place.

The fingers a, fingcnbar A, and cutter-bar B are of ordinaryconstruction and operation.

A case, 0, secured to the finger-bar, projects over the cutter-bar andholds the latter in 0 fits in between the posts e and e, and the catchor lever E is pivoted at one end to the (No model.)

points of attachment between it and the rods F shall be at adistanceapart, as shown at g. The free end of thelink is pivotallyconnected with the cutter-bar g.

The rods or bars F and G are so disposed that the free end 7 of the linkmoves in a straight linc,.always remaining parallel to a line passedtransversely through the normal position of said end or point 9. Inpractice the end 9 is bent at'right angles to the link and enters anopening, I), in the cutter-bar. It is evident that as many of theseattachments may be provided as is necessary, and that they may belocated at any point or points found most convenient.

It must be observed that the length of the rods or bars F is equal tothe distance between the points 9 and y,-. also that the rods incline orgradually approach each other from the points f to their pivotalconnections with the link. The points fare fixed relative to thefinger-bar and the point 9 fixed relative to the cutter-bar. In theoperation of the latter the bars F are vibrated about the points f, andthe distances between thepointsf and the point g vary proportionally tothe inclination of the rods in such a manner as to cause the point y tomove in a straight line, which at all times will be parallel to a linedrawn through or between the points f f.

While the case is shown attached to the finger-bar, it is evident thatthe parts may be reversed without departing from the spirit of myinvention.

Having thus described my invention, what I claim, and desire to secureby Letters Patcut, is

1. The combination, with a finger-bar and cutter-bar, of a pair of rodsor bars pivoted on the finger-bar,and a link. pivotally connecting thetwo and pivoted to the cutter-bar, whereby the cutter-bar is steadied inits longitudinal movement and the abrasion between its rear 8. Thecombination, with the finger and cutter bars, the pair of rods and alink pivotally connected at one end with the adjacent ends of the rods,of a case inclosing the rods and link, provided with lugs c and the lugc, the 20 casting D, having lugs to engage lugs c, and a catch tocontact with lug 0', whereby the bars; link, and cutter-bar areremovahly held in place, substantially as set forth.

In testimony whereofI affix my signature in 25 presence of twowitnesses. LEONARD STUDY;
